Definitions

  • This invention relates to feeding and distributing apparatus for charging a tower silo, particularly with agricultural bulk material, such as silage or the like, by means of material-handling fans.
  • Austrian Patent Specification 231,348 discloses apparatus which comprises an exhauster, which is mounted at the top end of a suction pipe and consists of a rotary distributor. That known apparatus also fails to ensure a trouble-free charging.
  • the use of rotary distributors disclosed in U.S. Pat. Nos. 2,474,205 and 2,365,240 also cannot prevent a clogging of a pipe.
  • Similar remarks are applicable to conveyors in which an upper pipe is at least in part of its length larger in diameter than a lower pipe, as has been disclosed in U.S. Pat. Nos. 772,124; 2,365,240; and 3,675,796.
  • This object is accomplished according to the invention by the provision of at least two fans which are disposed one above the other and comprise a lower fan, which has an intake passage communicating with a feeder and a delivery passage connected by a substantially vertical pipeline to an intake passage of an additional fan, which is disposed in known manner on a level near the top level of the silo and communicates at its outlet with a rotary distributor.
  • the fan disposed at the top of the silo consists in known manner of an exhauster and has a vertical axis and is coaxial with the vertical pipeline and is provided with a horizontal delivery conduit, which in known manner leads to the rotary distributor and is adjustable in length and pivotally movable in unison with the blower housing and adapted to be fixed in a plurality of positions. That arrangement may be used to charge a plurality of silos disposed one beside the other.
  • the rotary distributor mounted at the end of the horizontal delivery conduit communicates with or consists of a cyclone and the cross-section of the air outlet opening of the cyclone is adjustable.
  • a plurality of fans for use with particularly tall silos, a plurality of fans, usually three fans, may be provided, which are vertically spaced apart.
  • the intake passage of the or each intermediate fan is connected to a bend or an inclined portion of the pipeline.
  • the fan disposed at the level of the top of the silo is arranged as described hereinbefore and is pivotally movable.
  • the pipeline is provided with air intake openings, which are distributed around the periphery and, if desired, over the height of the pipeline and can be varied in cross-section.
  • an upper pipe of the pipeline is larger in diameter at least in part of its length than a lower pipe, as is known per se, and the lower pipe extends into the upper pipe and defines a circular annular intake opening therewith.
  • the cross-section of the intake opening can be varied by the provision of an upwardly tapering, adjustable ring, which can be fixed in several positions in which it is spaced different distances apart from the intake opening.
  • an intake opening which consists of a plurality of known apertures, which are spaced vertically and around the periphery of the pipeline and can be covered at least in part by a slidable sleeve fitted on the pipeline.
  • FIG. 1 is a side elevation showing the apparatus
  • FIG. 2 a top plan view
  • FIG. 3 a detail of the embodiment shown in FIGS. 1 and 2, and
  • FIG. 4 a detail of a modified embodiment.
  • a fan 2 is provided near the floor and can be fed manually via means 2' comprising a trough or a mechanical metering device comprising a belt conveyor or a screw conveyor provided with a trough. These metering devices ensure a uniform feeding of the fans so that the capacity of the latter will be utilized to a higher degree.
  • the lower fan 2 is a blower and on its delivery side its housing is only slightly eccentrically enlarged at 3 relative to the impeller 4.
  • Chopped heavy green forage which is to be fed is thrown up in a vertical pipeline 5 by the impeller 4, which comprises a plurality of moving vanes.
  • the conveyance of the forage is assisted by the air which is taken in.
  • the stream of material slows down as it rises in the pipeline and is subsequently accelerated by the suction exerted by a fan 6, which is disposed on the level of the top of the silo so that the forage is thrown to a larger total height.
  • the use of the invention effectively prevents an increasing deceleration of individual crop particles above a certain level and results in an acceleration of the entire stream of material toward the upper fan 6.
  • the total height to which the crop can be raised by means of a certain power is much increased and the danger of an undesired clogging of pipes is much reduced.
  • the fan 6 having a vertical axis and disposed approximately on the level of the top of the silo is designed to handle air at a relatively high rate. This is accomplished in known manner by an appropriate design of the housing and impeller of the fan.
  • the vertical pipeline 5 is provided with air intake openings 7, 7', which are preferably provided with means to adjust the total cross-section of said openings.
  • the air intake openings 7' of the pipeline 5 shown in FIG. 4 are spaced apart vertically and in the peripheral direction of the pipeline and can be covered at least in part by a slidable sleeve 8, which is fitted on the pipeline 5.
  • a slidable sleeve 8 which is fitted on the pipeline 5.
  • an air intake opening 7 has the configuration of a circular ring and is defined between an upper pipe 5' and a lower pipe of the pipeline 5.
  • the upper pipe 5' is larger in diameter than and receives the top end portion of the lower pipe.
  • the intake cross-section is adjustable by a tapering ring 9, which can be fixed in position.
  • a lower fan 2 consisting of a blower and a fan 6 disposed on the top level of the top of the silo and consisting of an exhauster does not only result in an improved performance, particularly in a feeding over a larger height, but affords also the advantage that the driving power is divided and can be generated by different sources.
  • the upper fan 6 is driven by an electric motor 10 and the fan 2 on the floor by a tractor motor 15 or by a tractor-mounted diesel engine. This advantage is significant in numerous farms where the power supply is inadequate in most cases and the connected load often must not exceed 10 kW.
  • the fan 6 disposed on the top level of the silo delivers the crop through a delivery pipe bend or a short horizontal delivery conduit 11, which is provided at the end with a known distributor, e.g., a rotary distributor 12 for discharging the crop into the silo.
  • a known distributor e.g., a rotary distributor 12 for discharging the crop into the silo.
  • Such permanently installed plant can be used to charge a plurality of silos which are juxtaposed or arranged in groups if the horizontal delivery conduit and the rotary distributor 12 as well as the housing of the blower 6 are capable of a pivotal movement at least within a limited range and adapted to be fixed in positions associated with respective silos.
  • the horizontal delivery conduit 11 consists of a telescopic tube.
  • That conduit When the delivery conduit 11 has been pivotally moved to the center of the respective silo, that conduit can be fixed in position by positioning linkages, which are supported on the silo wall or on a bracket which carries the fan. These linkages are not shown.
  • the adjustment may be effected by means of pull ropes or pull chains which are operated from the floor. It will be understood that other means, such as an electric motor, may be used to adjust the delivery conduit.
  • the rotary distributor 12 provided at the end of the delivery conduit 11 communicates with a cyclone or the top of the distributor consists of a cyclone 13 which can discharge surplus air in an upward direction.
  • the air which enters the silo cavity together with the crop assists the distribution of the forage but as the silo cavity is increasingly filled a major part of the air must be discharged upwardly by a cyclone.
  • the cross-section of the upwardly facing air outlet opening is adjustable at 14 in order to enable an adaptation to the degree to which the silo has been filled.
